EXPERIMENT
Another typical application of the 270M is the measurement
of
the spectral output of
something emits light. This could be a lamp,
or
the sun,
or
a laser diode, a glow
discharge, ....
or
whatever. If the source is stable over the range of seconds
to
minutes,
or
can be pulsed reproducibly, the 270M can be scanned
to
sequentially present the
wavelengths
to
the detector for measurement.
In this case, using a controller or computer, the start and end wavelengths, as well as
the scan speed and wavelength increment between datapoints are programmed.
